Yeah I guess in this case you were orphaned and you have to do the manual version. There are instructions in the earlyaccess threads. For users of 253 earlyaccess, Roonlabs wrote that they would update everyone automatically to 254 production, so that people wouldn’t get stranded on an abandoned branch (as RoonOS doesn’t get the regular updates like Roon), but this hasn’t worked for everyone so far, either. I guess something similar happened to you.
